Rectangular 4780

The television studio plan is made on a scale of 1:150. It shows a rectangular studio measuring 5 cm and 6 cm. If we pay 356 crowns for 1 m² of floating floor, how many crowns will we pay to cover the studio with a floating floor?

Correct answer:

x =  24030 Kc

Step-by-step explanation:

$$\begin{gathered} k=150/100=\frac{3}{2}=1.5 \\ a=5\cdot k=5\cdot 1.5=\frac{15}{2}=7.5\text{m} \\ b=6\cdot k=6\cdot 1.5=9\text{m} \\ S=a\cdot b=7.5\cdot 9=\frac{135}{2}=67.5{\text{m}}^2 \\ x=356\cdot S=356\cdot 67.5=24030\text{Kc} \end{gathered}$$
